Melamine-Spiking "Widespread" In China; Human Food Broadly Contaminated (4 comments )
Who knows what kind of crap is adulterating our imported and domestic food supply? But whatever it is, it's about to hit the fan.

Months after dogs and cats started dropping dead of renal failure from melamine-tainted pet food, American consumers are beginning to learn how long and how wide this contaminant has also poisoned the human food supply.

Last week, as California officials revealed that at least 45 people are known to have eaten tainted pork, the USDA announced that it would pay farmers millions of dollars to destroy and dispose of thousands of hogs fed "salvaged" pet food.

But this is just the tip of the iceberg. Through the salvaging practice, melamine-tainted pet food has likely contaminated America's livestock for as long as it has been killing and sickening America's pets -- as far back as August of 2006, or even earlier. And while it may seem alarmist to suggest without absolute proof that Americans have been eating melamine-tainted pork, chicken and farm-raised fish for the better part of a year, the FDA and USDA seem to be preparing to brace Americans for the worst. In an unusual, Saturday afternoon joint press release, the regulators tasked with protecting the safety of our nation's food supply go to convoluted lengths to reassure the public that eating melamine-tainted pork is perfectly safe.

In a fit of reverse-homeopathy the press release steps us through the dilution process, tracing the path of melamine-tainted rice protein through the food system. The rice protein is a partial ingredient in pet food, we are told, which is itself only a partial ingredient in the feed given to hogs, who then "excrete" some of the melamine in their urine. And, "even if present in pork," they reassure us, "pork is only a small part of the average American diet."

How comforting. But the press release reaches its Orwellian best in its insistence that there is no evidence of any "human illness" due to melamine exposure:

"While the Centers for Disease Control and Prevention systems would have limited ability to detect subtle problems due to melamine and melamine-related compounds, no problems have been detected to date."
Translation: "We are unable to detect such problems, but don't worry, no such problems have been detected."

It is hard to read this as anything but a preemptive press release, a calculated effort to reassure the public that it is safe to eat trace quantities of melamine... just days before they inevitably reveal that Americans have in fact been consuming it unawares for months. Menu Foods, the company at the center of the controversy, has recalled product dating back to November 8, 2006. Manufacturing forty to fifty percent of America's wet pet food, the salvaged product from their massive operations must have surely contaminated livestock feed nationwide.

And it gets worse. Tomorrow the New York Times will report from China, detailing how nitrogen-rich melamine scrap, produced from coal, is routinely ground into powder and mixed into low-grade wheat, corn, soybean or other proteins to inflate the protein analysis of animal feed:

The melamine powder has been dubbed "fake protein" and is used to deceive those who raise animals into thinking they are buying feed that provides higher nutrition value.
"It just saves money," says a manager at an animal feed factory here. "Melamine scrap is added to animal feed to boost the protein level."

The practice is widespread in China. For years animal feed sellers have been able to cheat buyers by blending the powder into feed with little regulatory supervision, according to interviews with melamine scrap traders and agricultural workers here.

[...] Many animal feed operators advertise on the Internet seeking to purchase melamine scrap. And melamine scrap producers and traders said in recent interviews that they often sell to animal feed makers.

"Many companies buy melamine scrap to make animal feed, such as fish feed," says Ji Denghui, general manager of the Fujian Sanming Dinghui Chemical Company. "I don't know if there's a regulation on it. Probably not. No law or regulation says 'don't do it,' so everyone's doing it. The laws in China are like that, aren't they? If there's no accident, there won't be any regulation."

"The practice is widespread in China," the Times reports, and has been going on "for years." And it is not just wheat, corn, rice and soybean proteins that should be suspect, but the animals who feed on it, including all imported Chinese pork, poultry, farm-raised fish, and their various by-products. Despite FDA and USDA efforts to allay concerns about consuming melamine-tainted meat, the health effects are unstudied, and the permissible level is zero. If China could impose a three-year (and counting) ban on the import of U.S. beef after a single incident of Mad Cow disease, then surely the U.S. would be justified in imposing a ban on Chinese vegetable protein and livestock products due to such a prevalent, industrywide contamination.

And if in the coming weeks this ban is finally imposed, the question we must ask government regulators is... why so late? Why did they wait until our children licked the last remaining drop of bacon fat off their fingers before alerting the public to the potential health risk, however low? It seems inconceivable that the regulators tasked with overseeing the safety and purity of our nation's food supply did not at least imagine the potential scope of this crisis back in early March when they first learned that Chinese wheat gluten was poisoning dogs and cats. Indeed, the very fact that they were so quick to focus in on melamine as the adulterating agent suggests they at least suspected what they were facing.

It may make for entertaining TV, but popular shows like CSI get forensic toxicology exactly backwards. You don't run a substance through a mass spectrometer and 30 seconds later get a complete readout of its chemical makeup. Rather, you painstakingly look for specific chemicals or groups of chemicals one at a time, until you find the offending toxin. Once you get beyond the basic "tox screen," forensics is as much art as science -- investigators use evidence and intuition to narrow the search to those compounds that are most likely to be the culprit.

And so it begs the question as to why -- in the face of an apparent wheat gluten contamination that reportedly killed nine out of twenty dogs and cats in Menu Foods' quarterly taste test -- would FDA scientists test for melamine, a chemical widely believed to be nontoxic?

Why? Because they thought they might find it.

Lacking adequate cooperation from FDA officials one is constantly forced to speculate, but given the circumstances it is reasonable to assume that the search for melamine was prompted by the "nitrogen spiking" theory, rather than the other way around. Based on their knowledge of the evidence, Chinese agricultural practices, the globalizing food industry, and perhaps prior history, the FDA hypothesized that unscrupulous Chinese manufacturers may have intentionally adulterated low quality wheat gluten in an effort to pass it off as a high-protein, high-value product. And nothing would do the job better than melamine.

According to one synthetic organic chemist, melamine is by far the perfect candidate. It is high in nitrogen (66-percent by weight), nonvolatile (ie, it doesn't explode,) and dirt cheap. It is also -- at least according to both the scientific literature and chemical supply catalogs -- widely considered to be nontoxic. For FDA officials, the mystery never seemed to be how melamine made its way into wheat, rice and corn protein, but rather, why it was suddenly killing dogs and cats.

The technical answer may center on the unexpected interaction between melamine, cyanuric acid, and other melamine by-products, but the practical answer may be much more pedestrian. Some samples of adulterated wheat gluten reportedly tested as high as 6.6-percent melamine by weight, an off the chart concentration that was likely the accidental result of some less than thorough mixing. Had this accident never occurred -- had cats, with their sensitive renal systems, not been the canary in the coal mine of melamine toxicity -- we might never have known that our children and our pets were being slowly poisoned by Chinese capitalism.

This is scary stuff...I stopped eating grocery store meats a long time ago, but the fish??? I eat farm raised fish at least 3x a week because to me it seems safer. I buy buffalo, pork, chicken and eggs from a local farm....what if their feed has been contaminated.

I almost wonder if terrorists are trying to poison our dogs as a test run for a large scale people poisioning

If China could impose a three-year (and counting) ban on the import of U.S. beef after a single incident of Mad Cow disease, then surely the U.S. would be justified in imposing a ban on Chinese vegetable protein and livestock products due to such a prevalent, industrywide contamination.

THIS is what makes me angry - the ONE mad cow case we had here, and China imposed a ban on ALL US beef and then they send us their absolute crap and expect us to eat it and feed it to not only our livestock, our dogs and cats but also our KIDS!!??
